- Small Semiconductor Heater
The heaters are used in enclosures where condensation is to be prevented or the temperature may not fall below a minimum value. In this way, corrosion is avoided and an even temperature is ensured.

Determination of heating capacity for switch cabinets
P=Ax△TxK
P= Required heating capacity(W)
A= Complete free-standing or heat losing surface of switch cabinet (m²)
△T = Temperature difference between the ambient temperature and the average desired internal temperature of the switch cabinet(k)
k= Heat transmission coefficient Lacquered steel sheet~5.5W/m²k Polyester ~ 3.5W/m²k
When used outside: double the calculated heating capacity
■ Many various heating capacities, from 10W to 55W
■ Heating element: PTC
■ High efficiency
■ Power save and safe
■ Used pressure clamp terminal blocks in order to get wiring save time
